Potassium hydroxide occurrence

I) derived from this by dissociation, or in a mobile equilibrium mixture of both these forms. Dobbie et reproduced the spectra of cotarnine solutions containing varying amounts of potassium hydroxide by using cotarnine chloride and hydrocotamine and by dissolving mixtures of the latter two compounds or by placing the separate solutions of these compounds in the apparatus in series. Thus no evidence could be obtained for the occurrence of the amino-aldehyde (3) postulated by Roser. Steiner, Kitasato, and Skinner came to similar conclusions. The band at 285 m/x in alkaline solutions is not due to an aromatic aldehyde. This band also occurs in the spectrum of hydrocotamine (10a) and in the carbinolamine... 

Potassium chloride is the most important salt of potassium from the perspective of its abundant occurrence and apphcations. This salt, along with potassium sulfate, is used heavily in fertilizers as the primary source of potassium, an essential element for crops. Over 90% salt manufactured is consumed as fertilizer. Also, potassium chloride is a raw material for producing potassium metal and several important potassium salts including potassium nitrate, potassium hydroxide, and potassium sulfate. Other applications are in electrode cells photography buffer solutions and measurement of salinity in water. 

The Raney alloy... are leached in aqueous alkaline solutions to remove aluminum. The preferred solutions are dilute aqueous solution." of sodium or potassium hydroxide. Aluminum reacts with the aqueou. -caustic solution, resulting in the formation of hydrogen. If hot or concen trated solutions are used, reaction proceeds very rapidly with the immediate evolution of large quantities of hydrogen. This destroys the desired mechanical structure of the product. To prevent this occurrence, the leaching is instituted in relatively cool and dilute aqueous caustic solutions, i.e., initial room temperature leaching with solutions... 

Spectroscopy has been used widely in investigating ion association, although it seems applicable only in cases where there is some orbital overlap of the associating ions. There are several systems where only electrostatic interaction is postulated and there are no detectable deviations from Beer s Law, but other evidence shows the occurrence of association. Examples of such systems are sodium and potassium tetra-phenylborate, thallous hydroxide and various tetralkylammonium halides. ...
